You have to extract the data from the string. The string "-128" is not equal the number -128 - it is a basic knowledge you have to understand even before writing your first hello_world. You have to split the string on the coma character and then convert substrings with toInt(), cast to uchar and append to byte array.
Is this icon looking like a flag (dark blue checkerd rectangle in the left top corner)? Because this is what I got from this string.
